Uniaxial Complex Relative Permittivity Tensor Measurement of Rocks From 40 Hz to 4.5 GHz
IEEE Transactions on Geoscience and Remote Sensing, 2017We develop a set of combined measurement techniques and calculation workflows to determine the complex uniaxial dielectric tensor of a rock sample from 40 Hz to 4.5 GHz. This unique method provides the ability to develop interpretation models bridging electrical logging tools with their corresponding operational frequencies and measurement direction ...

The Contemporary Definition of Complex Relative Permittivity
Journal of ASTM International, 2008Abstract ASTM D150 [Standard Test Methods for AC Loss Characteristic and Permittivity (Dielectric Constant) of Solid Electrical Insulation, 2004] is the standard for measurement of alternating current (AC). Aimed at an analysis of this standard and proceeding from the information transmission characteristic of the dielectric, the ...

Equations for Complex Relative Permittivity of Saline Water
IETE Technical Review, 1988Equations hare been presented to calculate the complex relative permittivity of saline water as a function of salt content and temperature of water. The results obtained from these equations show good agreement with the published measured data.

AbstractFrom the measurement of a reflected voltage waveform from a biological body for a step‐like voltage waveform, the frequency characteristics of the complex relative permittivity are studied and the following results are obtained: (1) if the blood flow and sweating are normal, the value of tanδ in the mouth is 4 ‐ 6 at about 10 MHz because ...
